scales, and the primary object thereof is to provide a thoroughly eflicient means for, computing the cost of a weighed article at a,

predetermined price per pound, said means enabling the salesman to quickly ascertain the cost of the article.

In computing scales it has been found that when the predetermined. price per pound of an article is above thirty cents that when one computing cylinder is employed that the graduations for the higher priced goods cannot be arranged in a satisfactory manner for view, under such conditions causing a slight confusion and loss of time when a. salesman endeavors to ascertain the weight and cost of a high priced article, and to this end the invention resides primarily in set ting up a computing scale mechanism whereby the salesman cannot only quickly ascertain the cost of a low priced article after being weighed, but can quickly ascertain the cost of a high-priced article, after weighing, Without loss of time or confusion.

A further obj ect of the invention is to provide a computing scale mechanism not only including means for quickly setting up a visible indication of the cost of a low or high" riced article, as well as the weight thereof. through the drum casing of the whereby the weight of the article will be visibly indicated from either end of the scale. Although the-scale mechanism is de-- signed primarilyv for use in weighing and computing the cost of an article, yet it is to be understood that it can also be adapted for use in connection with the Weighing and computing the postage necessary for the parcel post. v

Further objects of the invention are to provide acomputing scale mechanism, for weighing and computing low and high priced articles, which is simple in its construction andarrangement, strong, durable, efficient and convenient in its use, indicating the weight of the weighed article from each end and from ts side, readily set up and comparatively inexpensive to manufacture. lVith the foregoing and other objects in view the invention resides in the novel construction, combination and arrangement of parts as hereinafter more specifically described and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the claims hereunto appended.

The graduations for. computing the cost of .low riced articles" are visible through the opening 13. Thedriim 61 is furthermore provided with graduations for indicating the weight Qt -the article and such graduations are exposed through the opening 11. The webs 59, 60

are fixedly secured to the inner'face of the v drum 61 and, said web 59 is provided with an'extended hub- 62 for the shaft 68. .Fi'xe'd to the shaft 58 between the bearing 15 the hub 62 is a pinion 63 which meshes'with a vertically disposed reciprocatory rack 64,

the latter being guided by the support 42 v l and bar 46. The lower end of the'rack. 64

has formed integraltherewith a pulling arm 1 65 which extends through an opening 6.6, in the flange 22 of the ring 19 and which has its lower end connected to the otherend of the coupling bar 56. That end of the shaft 58 which pro ects beyond the disk 27 is.

provided with a pointer 67 which associates with the graduations 34 and is carried around with the shaft 38 and drum 61. The space 33 provides a clearance for, the pointer 6 The pinion of less diameter than the I I pinion 63, whereby the drum 50 will revolve faster than the drum 61,'by way of example, the ration is two to one, but this ratio-can be increased or diminished if desired. But;

two drums 50 and 61 are illustrated, but it is obvious that the number of drums can be increased if it be desired. The drums 50 and 61 are so set up thatthey will revolve in unison, but thedrum 50 at a, greater speed than the drum 61. Thedruni 50 on one revolution has its graduations to provide for the weighing and computing of from one to ten pounds, while the drum 61 has its graduations so arranged as toprovidc for the weighing and computing-of from one to twenty pounds. The number of pounds weighed and computed by the drum 50 can be increased or diminished if desired, and a like arrangement can be had with respect to-the drum 61, but preferably the drum 61 is adapted to weigh and compute the cost of low pricedarticles with a weight from one totwenty pounds and with a cost of from-two cents to thirtycents per pound, and-theldrum 5 0 is adapted to weigh and compute the: cost of high priced articles,

weighingjfrom one to ten pounds and costing fromthirty-one to sixty cents per pound.

racks 53 and '64- are rciprocated in one'direction through the medium of a vertic'all y'-movable operating arm 68 which is jfi'x'ed at one end-to the coupling bar 56 and 49;

i's%als.oj fixed to 'a coupling rod 69 arranged .below the coupling-bar 56. The operating rangement of parts it is obvious that the p {rm-68 is attached'as at 70 to an operating mechanism therefor (not shown) and which is arranged in the scale base (not shown).

The'coupling rod 69 at each end has fixed thereto .;a vertically-disposed pull bar 71, connected-at its upper end to across head to which is'attached the lower ends 73 18 and 19. The function of the springs 74 is to return the shafts 47 and 58 to normal position, that is to say, when the article has been weighed and removed from the scale.

A pair of springs 74 associates with the I i shaft 47 and a pair of springs 74 associates with the shaft 58. One pair of springs is arranged rearwardly of the disk 56 and the other pair is arranged rearwardly of the disk"2 7.

' From the foregoing construction and aroperating mechanism which is connected to the operating arm 68 will cause the operation of the drums 50 and 61 in unison, and that whena salesman is weighing and computing low priced goods, that end of the scale in which is arranged the druin 61 and the graduations 34 will be employed, and that when the operator is weighing and computing the cost of high priced goods,

I that the drum 50 and the graduations 36 will be employed.

The casing 10 is provided with indica- ,'tions, as-at SQ-tofdesignate the Price per pound of low priced goods, and the casing 10 is furthermore provided with indications,

or a fraction of a pound over ten pounds,

if the goods should weigh a fraction of a pound over ten pounds.

Referring to'Fig. 2 of the drawings the casing 10 is. formed of two sections 84: and 85, the former associating with the high priced graduated drum 86 and the latter with the low priced graduated drum 87, The sections 84:, 85 are provided with openings corresponding to'the openings 11 and 12 and slots corresponding to the slots 13- 14. The sections 84 and 85 are provided with indications similar" to the indications upon the periphery of the casing 10. Interposed between the sections 84, 85 is a hou ing 98 having each end for ed with an .an-

nular flange 88 which exte d in and are secured to ,the inner face of the sections 8 4, 85 at the inner ends thereof; Each end of the housing 98 is formed with an inwardly ex-' I its lower end provided with a bearingf92.

Fixed to the offset portion 90 is a hanger 93 having its lower end provided with a bearing 94, v

The reference characters 95, 96 denote a pair of operating shafts, the former for the low priced drum 87 and the latterfor the highpriced drum 86. The shafts 95 and 96 are supported in the saine manner and the description of the support of one will apply to the'description of the sup ort of the other. Eachfo'f the shafts 95, 96 i connected. to .its respective drum by a pairl of webs 100, 101 and one end of theshaft is ounted in a transverse bar 102 which is fi edly secured to its respective casing sec ion and which provided with a bearing 103 for I the end of the shaft. The shaft, at its inner end is mounted in the'bearin 92 and provided with an extendedhub 104, Each shaft projects from its bearing 103 and has fixedly secured thereto, so as to rotate there-- with, a disk 105 provided with graduations 106. The disk which is carried by'the shaft ing pounds from one to ten, and the'disk carried by the shaft 96 is proyide d with graduations for indicatingpounds from one to twenty. .1 i

Ifdesired parcel post gradua'tions can be arranged upon the disks at'each end of the casing that incloses the-computing scale mechanisms as set forth. Byutili'zing two or more; drums for the computing graduations, and revolving the high priced computing 'drumx'at less speed than the low priced computing drum and reducing the number of pound indications upon the high priced computing drum, the gradnaticns can be made very much larger so that no confusion will be had or time lost when a salesman desires to ascertain compo tation of the cost of the article Weighed.

The scale mechanism as illustrated and described not only provides visible indications of the Weight at the side of the scale but also from each end thereof.
